•Several challenges limit SOC measurement accuracy and reliability.•Spatial heterogeneity, especially on rangelands, drives SOC measurement uncertainty.•Small sample sizes are unreliable for detecting and quantifying expected SOC changes.•Non-parametric statistical methods are more reliable than t-t...
